You just can't beat this easy and delicious homemade Triple Berry Pie! It holds together perfectly every single time, and you can use fresh or frozen blueberries, raspberries and blackberries.
If you've tried any of my other favorite pie recipes, you may have learned that I'm a Pie fanatic! It's the most important part of my Thanksgiving. Don't miss my classic Pumpkin Pie, Apple Pie, and Lemon Meringue pies.

On Thanksgiving, I take great care not to over-stuff myself during dinner so that I have plenty of room for pie. And no, I don't just pick one favorite and enjoy a slice. I request slivers of nearly every single kind of pie (which, growing up, meant like 15-20 different kinds!).
My Mom mastered this Triple Berry Pie years ago. It's always the first gone at Thanksgiving–even for my husband who usually detests berries with seeds in them.
This pie is restaurant quality! Scratch that. It's BETTER than restaurant quality, because it's made from scratch! The crust is my Grandma's “Prize Winning” pie crust recipe, which couldn't be easier to make.
For the filling, I use the big beautiful frozen berries from Costco. They come in a 3-berry pack in the frozen section and the price is unbeatable. They are the biggest, nicest frozen berries I've ever seen. Don't you just love Costco?!
How to Make Perfect Berry Pie:
Cook berries: Simmer berries, sugar and lemon juice in a large saucepan over medium heat until warm and juicy, about 5-10 minutes, gently stirring occasionally.

Thicken filling: Spoon out about ½ cup of the juice from the pan into a bowl. Stir cornstarch into the juice until smooth. Bring pot of berries back to a simmer and slowly pour in the cornstarch. Gently stir mixture (being careful not to mash the berries), until thickened, about 2-5 minutes.
Cool. Remove from heat and stir in the butter. Allow to cool for 15 minutes.

Add to pie shell: Pour mixture into unbaked pie shell (in a 9 in deep dish pan). Add lattice top or a whole top with holes pricked on top for steam to escape. Pinch the edges of the top and bottom pie crusts together and crimp the edge, if you like.
Brush with egg wash: Brush a thin layer of beaten egg white over the top of the pie and sprinkle lightly with sugar.
Bake at 400 degrees F for 40-45 minutes. Check it after about 25 minutes and place a piece of tinfoil over it if the top crust is getting too browned.
Serve or refrigerate. Remove to a wire cooling rack and allow to cool for several hours. Once cooled completely, you can cut into it or cover it and refrigerate it overnight to serve the next day.

What sets this Berry Pie apart?
- Less sugar. It has way less sugar than most berry pies. It's still amazingly sweet, but it's not overly sweet, like some berry pies tend to be.
- Holds it's shape. It has the perfect amount of liquid to yield a pie slice that holds its shape. Some berry pies are so juicy that they completely fall apart when you cut into them. This one will turn out beautifully, as long as you let it cool for several hours before cutting into it.
So there you have it. Our family's favorite Triple Berry Pie. Perfect for Thanksgiving or Christmas or any time you're craving some pie…which, for me, is ALWAYS.

How to Make a Lattice Crust:
Don't let this beautiful pie crust intimidate you! It's so easy, especially if you know the tricks!
- Roll out crust. Roll our your homemade crust on a lightly floured counter or on a piece of parchment paper. (I like to place a piece of parchment paper on top of a damp kitchen towel to keep it from moving around). Roll the pie crust into a large circle that's about 1-2 inches larger than then top edge of your pie dish.
- Cut strips. Use a pizza cutter to strips. cut them as wide as you'd like them to be (there's really no right or wrong way).
- Lay first layer of strips. Lay your longest strip across the middle of the pie then lay a few shorter strips on either side, parallel to each other and spaced evenly.
- Fold pack even numbered strips. Fold back the second and 4th strip and lay a shorter strip of dough perpendicular to other dough strips. Unfold those dough strips over the new strip.
- Fold back odd numbered strips: Fold back the first, third and fifth strips in the same direction and lay another dough strip across the pie. Unfold the first, third and fifth strips over the new strip.
- Repeat steps 4 and 5 until pie is covered with a lattice crust.
- Trim dough strips.
- Pinch crusts together. Pinch the lattice top with the bottom crust to form one unified outer edge.
- Crimp edges.

Make Ahead and Freezing Berry Pie:
To make ahead: This pie can be prepared completely 1 day a head of time. You can also prepare the filling up to 3 months ahead of time and store it in the freezer. Thaw it overnight in the refrigerator before pouring in unbaked pie crust.
To freeze: You can freeze the baked pie for up to 3 months. Thaw overnight in the refrigerator and allow to come to room temperature before serving.

Five stars all day long! All winter I’ve been staring at a shelf full of frozen berries, and I chose this one to try. No reason to look elsewhere, this one is my keeper! I used strawberries, blackberries, huckleberries, raspberries, blueberries and cranberries! OH MY! It set up beautifully and tastes amazing. Not cloyingly sweet; just right for us! All wrapped up in your Perfect Pie Crust recipe, this goes into my Best of the Best File. I’ll be putting the Granddaughters to work picking berries again this summer! Thank you for sharing this lovely recipe!
When do you add the butter?
Hi, Kya. I saw your question scrolling down — I missed the butter directions, too. I am accoustomed to recipes that say to dot the filling with cut-up butter before putting on the top crust. But I didn’t see that in the directions here and I thought it was an oversight. So I just dotted it with butter the way I usually would, on top of the filling but under the top crust. But, re-reading the recipe, I see the butter is to be stirred into the hot, thickened filling (#5 in the filling directions) before cooling. I am sure this mixes in the butter with much greater uniformity, so I will denitely do this when I make it again.
All I can say is WOW!!! This recipe is so easy and the pie is perfect and utterly delicious. I’m so happy I found this recipe…this will be the only Triple Berry pie I make from now on.
DELICIOUS!! Thank you for a great recipe that a novice can make successfully!! Was a hit with the family at Thanksgiving.
Very easy to make but did add more fruit
I’ve been making this pie for a couple years now, and I’m always asked to bring it for Thanksgiving and Christmas dinners. It’s also my go to pie when I just feel like baking. And the kids love it too! I used store bought pie crust this time, so hopefully it turns out well!
Hi Lauren! I’m hoping to make this pie and freeze it for about a week. Do you have tips for properly wrapping the pie for freezing? Thanks! Look delicious.
I would wrap it in plastic wrap and then aluminum foil.
This pie is amazing! I made your homemade pie crust before and it’s come out really really good. So I used your crust recipe and this berry recipe and it was amazing. I found a frozen berry mix that included strawberries, blackberries, raspberries, and blueberries. I attempted a lattice crust for the first time and it looks OK. I need to practice to make it look a little prettier but the taste was amazing.
I took about 2 tablespoons of sugar out of the berry mixture because I personally prefer a more tart berry and I could always add it back in if needed. I tasted it and I thought it was perfect. Thank you for the amazing recipe and I will make all my pies with your crust recipe.
Made your triple berry pie exactly to your recipe and it came out great.
Only thing I used different in the crust was pure rendering leaf lard. The crust is beautiful. Will be a pie on my list to make often.
Thanks
Great Pie! Always get requests for it. Easy too!
Very good recipe! I just made it for MI birthday, everyone loved it! I didn’t use the butter in the filing though. Does it improve the flavor or change the texture?
Anyways, great recipe! Easy to make and very convenient for when it’s not berry season!
Thanks!
I was looking for a recipe to use up an aging bag of Costco frozen mixed berries and discovered this one. Instead of using the filling for a pie, I freeze it in 1 cup portions in plastic bags for a wonderful topping on pancakes or waffles. It is also fantastic as a garnish on Chocolate Lava Cakes with a dollop of whipped cream! Yum!!
Great recipe! Easy to follow and it comes out great. Everyone who’s tried it didn’t believe I had made it.
